+Subject: [PATCH] kexec: Add quick kexec support
 
+Add quick kexec option -q and flags.
+
+In normal kexec, relocating kernel may cost 5 ~ 10 seconds, to
+copy all segments from vmalloced memory to kernel boot memory,
+because of disabled mmu.
+
+We introduce quick kexec to save time of copying memory as above,
+just like kdump(kexec on crash), by using reserved memory.
+
+We also add this support in syscall kexec_load of linux kernel
+through flags of KEXEC_QUICK.
